CanPrev Pro-Biotik 15B - A shelf-stable probiotic formula containing five critical probiotic species naturally found in the human intestinal tract, including bifidobacteria and lactobacilli. Each species is represented at optimal levels to enhance the natural gut flora and provide a health benefit. Probiotics are beneficial bacteria, or live microorganisms, that work by colonizing the small and large intestines and inhibit the growth and activity of harmful organisms. They have been found to stimulate the immune system and enhance the absorption of certain nutrients. Research shows that certain strains can be helpful for restoring a healthy gut flora after the use of antibiotics and in cases of diarrhoea.
